如何复制到剪贴板，ListView的多个选定项目？

This code is working for one single selected item: In the top:

此代码适用于单个选定项目:在顶部:

ContextMenuStrip menuStrip;

Then in the constructor:

然后在构造函数中:

menuStrip = new ContextMenuStrip();
menuStrip.ItemClicked += menuStrip_ItemClicked;
menuStrip.Items.Add("Cut");
menuStrip.Items.Add("Copy");
menuStrip.Items.Add("Paste");

The menuStrip itemclicked event:

menuStrip itemclicked事件:

ListViewItem item;
        private void menuStrip_ItemClicked(object sender, ToolStripItemClickedEventArgs e)
        {
            if (e.ClickedItem.Text == "Copy")
            {
                Clipboard.SetText(item.SubItems[1].Text);

            }
        }

Then the ListView mouse click event:

然后是ListView鼠标单击事件:

private void lstDisplayHardware_MouseClick(object sender, MouseEventArgs e)
        {
            if (e.Button == MouseButtons.Right)
            {
                item = lstDisplayHardware.GetItemAt(e.X, e.Y);
                menuStrip.Show(lstDisplayHardware, e.Location);
            }
        }

This code is working for single selected item. For example I click on an item in the ListView, right click on the item and select Copy: the selected item's subitem is copied to the Clipboard.

此代码适用于单个选定项目。例如,我单击ListView中的项目,右键单击该项目并选择复制:所选项目的子项目将复制到剪贴板。

But now I want to do the same thing for multiple selection.

但现在我想为多项选择做同样的事情。

So if I use Ctrl+Left mouse click and for example selected 4 items and invoke Copy command from the context menu, I expect all subitems of the 4 selected items text to be copied into the Clipboard.

因此,如果我使用Ctrl +鼠标左键单击并选择4个项目并从上下文菜单中调用复制命令,我希望将4个所选项目文本的所有子项目复制到剪贴板中。

For example I have these items:

例如,我有这些项目:

danny hello world
daniel hi all
dan rain today
daniels sunny day

丹尼你好世界丹尼尔喜所有dan rain今天daniels阳光灿烂的日子

I select the items:

我选择了这些项目:

danny
daniel
dan
daniels

丹尼丹尼丹丹尼尔斯

Then right click and click on Copy. When I paste anywhere from the clipboard I want it to show:

然后右键单击并单击“复制”。当我从剪贴板粘贴任何地方时,我希望它显示:

hello world
hi all
rain today
sunny day

你好世界你好今天阳光灿烂的日子

All of the sub items of the selected items in the same order and format.

所选项目的所有子项目的顺序和格式相同。

First, you have to enable multiselect:

首先,您必须启用多选:

ListView1.MultiSelect = true;

Then, you can get selected items with:

然后,您可以获得以下选定项目:

private void menuStrip_ItemClicked(object sender, ToolStripItemClickedEventArgs e)
{
    ListView.SelectedListViewItemCollection selectedItems = 
    ListView1.SelectedItems;
    if (e.ClickedItem.Text == "Copy")
    {
         String text = "";
         foreach ( ListViewItem item in selectedItems )
         {
              text += item.SubItems[1].Text;
         }
         Clipboard.SetText(text);
    }
}

#2

    private void listBox1_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.Control && e.KeyCode == Keys.C)
        {
            CopyListBox(listBox1);
        }
    }

    public void CopyListBox(ListBox list)
    {

        StringBuilder sb = new StringBuilder();
        foreach (string item in list.SelectedItems)
        {
            sb.AppendLine(item);
        }

        Clipboard.SetDataObject(sb.ToString());

    }

#3

For ListView, not ListBox code will be:

对于ListView,不是ListBox代码将是:

    private void listView1_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.Control && e.KeyCode == Keys.C)
        {
            CopyListBox(listView1);
        }
    }
    public void CopyListBox(ListView list)
    {
        StringBuilder sb = new StringBuilder();
        foreach (var item in list.SelectedItems)
        {
            ListViewItem l = item as ListViewItem;
            if (l != null)
                foreach (ListViewItem.ListViewSubItem sub in l.SubItems)
                    sb.Append(sub.Text+"\t");
            sb.AppendLine();
        }
        Clipboard.SetDataObject(sb.ToString());

    }
